John Ligonier, 1st Earl Ligonier

Field Marshal John Ligonier, 1st Earl Ligonier, KB, PC (born Jean Louis de Ligonnier; 7 November 1680 – 28 April 1770), styled Sir John Ligonier from 1743 to 1757, was a British army officer and politician who served in the English and British armies for more than half a century. In 1757, he was appointed Commander-in-chief and raised to the peerage as Viscount Ligonier in 1757, and in 1766, further elevated as Earl Ligonier.

Ligonier was a Huguenot refugee who fled his native Castres for England in 1697, following the 1685 Edict of Fontainebleau, which stripped the rights of French Protestants to practice their religion. He joined the British Army in 1702 as a volunteer and remained dedicated to the British cause for the next six decades. He fought in the European wars of the Spanish Succession, of the Quadruple Alliance, and of the Austrian Succession. During the Seven Years' War, he also served as Master-General of the Ordnance, effectively acting as Minister of War for the Pitt–Newcastle ministry. He retired from active duty in 1763 and died at his home in London on 28 April 1770.

He sat in the House of Commons of Great Britain for Bath from 1748 to 1763 and served as Governor of Guernsey from 1750 to 1752.
